5211.42.00.40 - Weighing more than 360 g/m² (225)

This HTS category encompasses blue denim fabrics that are woven from yarns of different colors, specifically where cotton is mixed with man-made fibers and the cotton content by weight is less than 85 percent. The defining characteristic of this classification is its weight, which is greater than 360 grams per square meter. These are substantial, heavy-weight blue denim fabrics, often utilized in the manufacturing of durable apparel such as workwear, heavy-duty jeans, and outerwear where robustness is paramount.

The distinction between this category and its sibling, 5211.42.00.20, lies solely in the weight threshold. While both fall under blue denim woven from yarns of different colors with a predominant cotton blend (less than 85% cotton), this specific code applies only to those fabrics exceeding 360 g/m². The sibling code, conversely, covers blue denim weighing 360 g/m² or less. This weight criterion is a critical factor in differentiating between lighter-weight fashion denim and heavier-duty industrial or workwear grades.

As a leaf node within the HTS structure, this category does not have further subdivisions. Therefore, classification under 5211.42.00.40 is definitive for blue denim fabrics meeting the specified composition (less than 85% cotton, mixed with man-made fibers, woven from yarns of different colors) and the critical weight requirement of exceeding 360 g/m². Importers and exporters should pay close attention to accurate weight measurements to ensure correct classification and compliance with customs regulations.
